UNITED STATES SHEET-DELIVERING APPARATUS FOR USE WITH PRINTING, CUTTING, AND THE LIKE MACHINES. v.

Application filed January 22, 1926, Serial No. 83,091, and in Great Britain February 25, 1925.

This invention is for improvements in or relating to a method and means for forming strips of paper or the like into a stack or stacks and more particularly to a method and means for severing a paper or like web into lengths and thereafter forming the successive strips into a stack or stacks.

The object of the present invention is to provide a method and means whereby strips of paper may be stacked in a simple and efiicient manner, the successive strips being preferably placed one under the other in ra id succession.

he present invention consists of a method of forming strips of paper or the like into a stack or stacks which comprises (a) Feeding the strips in line, with successive strips spaced apart or otherwise;

(1)) Moving successive strips out of line and into parallel relationship, and

(c) Advancing the successive parallel strips into surface contact with each other.

Further the present invention consists of a method of severing a paper or like web into lengths and thereafter forming the successive strips into a stack or stacks which comprises (a) Severing a web of paper or the like into strips;

(7)) Moving the successive strips out of line and into parallel relationship, and

(c) Advancing the successive parallel strips into surface contact with each other.

Again the present invention consists of strips of paper or the like when stacked by the method set forth in either of the two preceding paragraphs.

Further the present invention consists of a device for stacking strips of paper or the like which comprises means adapted to deliver the strips in line and means adapted to move the successive strips out of line and into parallel relationship and advance the successive parallel strips into surface contact with each other.

Again the present invention consists of a device for severing a web of paper or the like into lengths and thereafter stacking the successive strips, which comprises means for severing a web of paper or the like into strips, means adapted to move the successive strips out of line and into parallel relationship and advance the successive parallel strips into surface contact with each other.

The device which constitutes the subject matter of the present invention will be hereinafter described with reference to an intaglio printing device wherein a travelling 7 web of paper, subjected to a multi-colour printing operation, is severed into strips or labels which are formed into a stack or stacks.

Referring to the drawings, a travelling web 1 which has been subjected to a multicolour intaglio printing operation is fed by means of a pair of rollers 2, to a cutting mechanism which comprises a rotary cutting blade 3 and a fixed cutting blade 4. The cutting mechanism is prefcrably constructed in the manner described in my (n-pending British patent application No. 25,810 of 15th October. 192:). and No. 29,880 of 26th November, 1925.

The web 1. as it passes between the rotary blade 3 and the fixed blade 4, above a bed 5 which is preferably constructed in the form of a hollow chamber adapted to receive air under pressure and emit the same through apertures 6 so as to form a cushion support for the web in its forward movement and prevent the printed surface of the web from coming into contact with the bed of the machine, and further it assists in drying the ink upon the web.

Mounted so as to rotate above the bed 5 is a suction drum 7, which is connected through the conduit 8 to a centrifugal pump which is adapted to draw air through the aperture 9 formed in the periphery of the drum.

leading edge of the web aptCl1S the suction drum 7 it is drawn by ction into contact with the periphery mere/of and is assisted forwardly by the reation of the drum.

T he drum 7 is carried upon a spindle 10, carries a sprocket wheel 11 adapted engage with a chain 12 which engages iii, a sprocket wheel 13 mounted on the die 14 which carries the rotary cutter 3. A spindle 14 is driven from the main at the machine and the chain 12 passes at the idler 15 for the purpose of rethe direction of rotation of the drum a iatively to the spindle 14. The sprocket 11 is adapted to drive the drum 7 at a heral speed greater than the speed of t avelling web 1 such that when the rise of the web is gripped by suc- Yhc drum 7 that portion of the web l between the feed rollers 2 and the ii I maintained in tension, thus enng that the web 1 is only severed into lst the portion of the web between rollers 2 and the drum 7 is held iliiil:

Adapted to engage with grooves formed in the periphery of the drum 7 are belts 7 iai-ls are adapted to engage with pulleys 1G and 17 mounted on spindles 18 and carried in such a manner that one porn of each belt is always supported in a al direction, Thus when a strip is 1 from the web 1, the drum 7 carries sure at a higher speed than the oncomiding edge of the severed web hus the strip from the w l me thrcugh F P: the Wed from thi 7 into U .1 i, strip drum and carried upon oriaontal position. In V e the web engages with wed in the lower end of four The discs 20 are provided with lrures 22 whirls are adapted to register iodically with the suction pipes 23 which w the strip down and ensures that each brought into engagement with the l and is arrested against any further nail movement.

lower ends of the spirals 21 are -11 of a coarser pitch than the upper tion and each severed strip, when drawn engagement with the discs 20, is ene-rl by the lower end of the spirals 21 supported at four points around its 1 as it is elevated quickly in a horizontal iwiion by means of the said spirals.

After the strip has been initially raised from the discs 20 it is carried by the upper portion and gradually raised to the top of the said spirals. The strips, which are supr ed round their edges by the said spirals, re their leading edges prevented from ing below the level of the discs 20 by flanges 24 which are mounted flush with tin; discs 20.

The ends of the strips which, as the strips are being elevated, are located above the drum 7, are adapted to engage with a guide member 25 and located adjacent to the other ends of the strips is a tubular element 26 adapted to receive air under pressure and emit the same through orifices 26*.

The tubular element 26 with the air jets emitted therefrom, tends to move the successive strips which are supported upon the spirals 21 against the guide member 25 and also assists the strips in the upward travel, at the same time subjecting the strips to a further drying operation.

Thus it will be seen that as the successive strips are cut from a travelling web they are moved by the suction drum into engagement with the spiral feeds 21, which move the successive strips in parallel relationship and advance them to the top of the said spirals where they are placed one under the other and formed into a stack.

Referring to the Figures 6' and 7, the guide member 25 mounted above the drum 7 is adapted to be moved towards and away from the tubular element 26 mounted (lirectly opposite. The movable guide member 25 is carried by two links 27 and 28, which are pivoted about spindles 29 and 30 carried by the machine. The pivotal link 27 is secured at a point along its length to a pivotal link 31, which is connected at its free end to a pivotal link 32, the free end of which is adapted to engage with a cam 33 connected to a spindle 34 through the medium of a ratchet and pawl 33" which permits the cam to be moved backwards by the knob 33*, This enables the cam to be moved to zero whilst the machine is running. The spindle 34 is driven by a worm wheel 35 which engages with a worm 36 formed upon the spindle 37. The spindle 37 is driven by a worm wheel 38 which engages with a worm 39 formed upon a spindle 40, which is driven from the main drive of the machine.

The double worm connection between the. cam 33 and the spindle 40 which is connected with the main drive constitutes a reduction of 500 to 1.

The cam 33 is divided into two sections such that in each complete revolution the cam moves the guide member 25 towards and away from the tubular element 26.

As the reduction in the drive is 500 to 1 it will be observed that the guide member 25 is moved forwardl and backwardly for every 250 strips which are fed to the spiral feed.

Thus it will be seen that with the arrangement hereinbefore described, the stack formed at the head of the spiral feeds is divided into batches of 250 strips each. It

will be appreciated that the drive between the cam and the main drive of the machine may be constructed to separate the strips in batches of any desired number.

The spiral feed and the driving mechanism therefor, are preferably constructed in a manner similar to that indicated in the accompanying drawings wherein the framework which supports the spirals and their drive is ivotally secured to the bed of the machine y a yoke 41 pivotally mounted on the spindle 10 upon which the suction drum 7 rotates. This feature permits the stacker to be swung into a horizontal position so as to facilitate the free manipulation of the cutting mechanism.
